Secretion into the cerebrospinal fluid by caudal neurosecretory neurons

Abstract

Neurons of the regenerating caudal neurosecretory system of Tilapia mossambica and of the normal system of Albula vulpes send processes into the central canal of the spinal cord. Evidence for appreciable release of secretion into the cerebrospinal fluid from these processes has been obtainied with both light and electron microscopes.
